Description

Technical Field

[0001] This application relates to the technical field of power distribution units, and particularly to a rack-mounted power distribution unit. Background Art

[0002] A rack-mounted power distribution unit (rPDU) is a power distribution and management device installed on a server cabinet, mainly used to distribute power from a single input to multiple outputs to meet the power consumption needs of various IT devices within the rack. The rack-mounted power distribution unit is widely used in data centers, network computer rooms, computer rooms and other places.

[0003] However, due to its own structural design, in the related art, as long as there is an overload in one of the multiple loads connected to the rack-mounted power distribution unit, all the loads connected to the rack-mounted power distribution unit will lose power. Therefore, it is necessary to design a new type of rack-mounted power distribution unit that, when a load is overloaded, only the power supply branch where the overloaded load is located loses power, while the power supply branches where the remaining loads are located can operate normally. Summary of the Invention

[0004] The embodiments of this application provide a rack-mounted power distribution unit, which can solve the problem that in the related art, as long as there is an overload in one of the multiple loads connected to the rack-mounted power distribution unit, all the loads connected to the rack-mounted power distribution unit will lose power due to its own structural design.

[0005] The embodiments of this application provide a rack-mounted power distribution unit; the rack-mounted power distribution unit includes a connection module, a socket module, a connection component, and a distributed switch unit. The connection module is used to connect to a power supply unit to receive a power signal. The socket module includes multiple socket units, and the socket units are used to connect to external devices to supply power to the external devices. The connection component is connected to the connection module to receive the power signal. The distributed switch unit is connected between at least one socket unit and the connection component, and the distributed switch unit is used to control whether the power signal from the connection component is provided to at least one socket unit.

[0006] Based on the rack-mounted power distribution unit of the embodiments of this application, by designing a distributed switch unit, the distributed switch unit has a conducting state and a cut-off state. The connection module, the connection component, the distributed switch unit, and the socket units of the socket module cooperate with each other to form a power supply branch. When an external device is overloaded, the distributed switch unit is in the cut-off state. At this time, only the power supply branch where the overloaded external device is located loses power, and the power supply branches where the remaining non-overloaded external devices are located can operate normally, so as to realize the shunt power supply control of multiple external devices connected to the multiple socket units of the socket module.

Detailed implementation manners

[0010] In order to make the objectives, technical solutions and advantages of this application clearer, the following further details this application in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0011] Please refer to Figure 1 - Figure 2 As shown, this application proposes a rack-mounted power distribution unit 1, which includes a connection module 10, a socket module 20, a connection component 30, and a distributed switch unit 40. The connection module 10 is used to connect to the power supply unit 2 to receive a power signal. The socket module 20 includes a plurality of socket units 20a, and the socket units 20a are used to connect to external devices to supply power to the external devices. The connection component 30 is connected to the connection module 10 to receive a power signal. The distributed switch unit 40 is connected between at least one socket unit 20a and the connection component 30, and the distributed switch unit 40 is used to control whether the power signal from the connection component 30 is provided to at least one socket unit 20a.

[0012] The following further expands and introduces the specific structure of the rack-mounted power distribution unit 1 in conjunction with Figure 1 - Figure 8 As shown, the rack-mounted power distribution unit 1 includes a connection module 10, a socket module 20, a connection component 30, and a distributed switch unit 40.

[0013] As Figure 1 - Figure 2 shown, the connection module 10, as the signal access structure of the rack-mounted power distribution unit 1, is used to connect to the power supply unit 2 to receive a power signal; among them, the power supply unit 2 can but is not limited to including the power grid. The specific structure of the connection module 10 will be further expanded and introduced below.

[0014] The socket module 20, as the signal output structure of the rack-mounted power distribution unit 1, includes a plurality of socket units 20a, and the socket units 20a are used to connect to external devices to supply power to the external devices; among them, the external devices can but are not limited to including electrical devices such as computers and air conditioners. The specific structure of the socket unit 20a will be further expanded and introduced below.

[0015] The connection component 30, as the electrical connection structure of the rack-mounted power distribution unit 1, the specific structure of the connection component 30 will be further expanded and introduced below.

[0016] The connection component 30 is connected to the connection module 10 to receive a power signal.

[0017] The connection component 30 is connected to the connection module 10 to receive a power signal.

[0018] The distributed switch unit 40, as the electrical on / off structure of the rack-mounted power distribution unit 1, the specific structure of the distributed switch unit 40 will be further expanded and introduced below.

[0019] The distributed switch unit 40 is connected between at least one socket unit 20a and the connection component 30, and the distributed switch unit 40 is used to control whether the power signal from the connection component 30 is provided to at least one socket unit 20a. For example, when only some of the socket units 20a among all the socket units 20a are connected to the connection component 30 through the distributed switch unit 40, at this time, the distributed switch unit 40 is used to control whether the power signal from the connection component 30 is provided to the corresponding socket units 20a (i.e., the aforementioned partial socket units 20a), while the remaining socket units 20a among all the socket units 20a are directly connected to the connection component 30 to receive the power signal. Another example is that when all the socket units 20a are connected to the connection component 30 through the distributed switch unit 40, at this time, the distributed switch unit 40 is used to control whether the power signal from the connection component 30 is provided to all the socket units 20a.

[0020] It can be understood that the distributed switch unit 40 has a conducting state and a cutoff state; when the distributed switch unit 40 is in the conducting state, at this time, the distributed switch unit 40 can control the power signal from the connection component 30 to be provided to the socket unit 20a, and the power supply branch formed by the connection module 10, the connection component 30, the distributed switch unit 40, and the socket unit 20a is conducting, and the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1; when the distributed switch unit 40 is in the cutoff state, at this time, the distributed switch unit 40 cannot control the power signal from the connection component 30 to be provided to the socket unit 20a, and the power supply branch formed by the connection module 10, the connection component 30, the distributed switch unit 40, and the socket unit 20a is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0021] The switching of the distributed switch unit 40 between the above-mentioned conducting state and the above-mentioned cutoff state can be achieved by manual control or by automatic control. Specifically, the manual operation can be achieved by the user manually pressing; the automatic method can also combine the detection unit to detect the operation conditions (such as voltage, current, and power conditions) of at least one module, module group, or unit of the rack-mounted power distribution unit 1, and automatically control the conduction and cutoff of the distributed switch unit 40 according to the detection results.

[0022] Based on the rack-mounted power distribution unit 1 in the embodiments of the present application, by designing the distributed switch unit 40, the distributed switch unit 40 has a conducting state and a cutoff state. The connection module 10, the connection component 30, the distributed switch unit 40, and the socket unit 20a of the socket module 20 cooperate with each other to form a power supply branch. When an external device is overloaded, the distributed switch unit 40 is in the cutoff state. At this time, only the power supply branch where the overloaded external device is located loses power, and the power supply branches where the other non-overloaded external devices are located can work normally, so as to realize the shunt power supply control of multiple external devices connected to multiple socket units 20a of the socket module 20.

[0023] As Figure 1 and Figure 3 shown, the distributed switch unit 40 includes a plurality of distributed switches 41. Each distributed switch 41 is connected between a corresponding socket unit 20a and the connection component 30. The distributed switch 41 is used to control whether the power signal from the connection component 30 is provided to the corresponding socket unit 20a.

[0024] Among them, each distributed switch 41 has a conducting state and a cutoff state; for each distributed switch 41, when the distributed switch 41 is in the conducting state, at this time the distributed switch 41 can control the power signal from the connection component 30 to be provided to the corresponding socket unit 20a, and the power supply branch formed by the connection module 10, the connection component 30, the distributed switch 41, and the corresponding socket unit 20a is conducted, and the power supply unit 2 can supply power to the external device through the rack-mounted power distribution unit 1; for each distributed switch 41, when the distributed switch 41 is in the cutoff state, at this time the distributed switch 41 cannot control the power signal from the connection component 30 to be provided to the corresponding socket unit 20a, and the power supply branch formed by the connection module 10, the connection component 30, the distributed switch 41, and the corresponding socket unit 20a is disconnected, and the power supply unit 2 cannot supply power to the external device through the rack-mounted power distribution unit 1.

[0025] As Figure 1 , Figure 2 and Figure 4 shown, the socket module 20 includes a first socket module 201, a second socket module 202, and a third socket module 203; the connection component 30 includes a first live wire connector L1, a second live wire connector L2, a third live wire connector L3, a neutral wire connector N, and a ground wire connector PE; the first socket module 201 is connected to the first live wire connector L1, the second socket module 202 is connected to the second live wire connector L2, and the third socket module 203 is connected to the third live wire connector L3.

[0026] The multiple distributed switches 41 include multiple first switches K1, multiple second switches K2, and multiple third switches K3. The multiple first switches K1 are respectively connected between the first live wire connector L1 and multiple socket units 20a of the first socket module 201. The multiple second switches K2 are respectively connected between the second live wire connector L2 and multiple socket units 20a of the second socket module 202. The multiple third switches K3 are respectively connected between the third live wire connector L3 and multiple socket units 20a of the third socket module 203.

[0027] Among them, the multiple first switches K1 and the multiple socket units 20a in the first socket module 201 are arranged in one-to-one correspondence, and each first switch K1 has a conducting state and a cut-off state. For each first switch K1, when the first switch K1 is in the conducting state, the first switch K1 can control the power signal from the first live wire connector L1 to be provided to the corresponding socket unit 20a in the first socket module 201, and the power supply branch formed by the connection module 10, the first live wire connector L1, the first switch K1, and the corresponding socket unit 20a in the first socket module 201 is conducted, and the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1. For each first switch K1, when the first switch K1 is in the cut-off state, the first switch K1 cannot control the power signal from the first live wire connector L1 to be provided to the corresponding socket unit 20a in the first socket module 201, and the power supply branch formed by the connection module 10, the first live wire connector L1, the first switch K1, and the corresponding socket unit 20a in the first socket module 201 is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0028] The multiple second switches K2 and the multiple socket units 20a in the second socket module 202 are arranged in one-to-one correspondence, and each second switch K2 has a conducting state and a cut-off state. For each second switch K2, when the second switch K2 is in the conducting state, the second switch K2 can control the power signal from the second live wire connector L2 to be provided to the corresponding socket unit 20a in the second socket module 202, and the power supply branch formed by the connection module 10, the second live wire connector L2, the second switch K2, and the corresponding socket unit 20a in the second socket module 202 is conducted, and the power supply unit 2 can supply power to external devices through the rack-mounted power distribution unit 1. For each second switch K2, when the second switch K2 is in the cut-off state, the second switch K2 cannot control the power signal from the second live wire connector L2 to be provided to the corresponding socket unit 20a in the second socket module 202, and the power supply branch formed by the connection module 10, the second live wire connector L2, the second switch K2, and the corresponding socket unit 20a in the second socket module 202 is disconnected, and the power supply unit 2 cannot supply power to external devices through the rack-mounted power distribution unit 1.

[0029] A plurality of third switches K3 and a plurality of socket units 20a in the third socket module 203 are arranged in one-to-one correspondence, and each third switch K3 has a conducting state and a cutoff state; for each third switch K3, when the third switch K3 is in the conducting state, at this time the third switch K3 can control the power signal from the third live wire connector L3 to be provided to the corresponding socket unit 20a in the third socket module 203, and the power supply branch formed by the connection module 10, the third live wire connector L3, the third switch K3, and the corresponding socket unit 20a in the third socket module 203 is conducted, and the power supply unit 2 can supply power to the external device through the rack-mounted power distribution unit 1; for each third switch K3, when the third switch K3 is in the cutoff state, at this time the third switch K3 cannot control the power signal from the third live wire connector L3 to be provided to the corresponding socket unit 20a in the third socket module 203, and the power supply branch formed by the connection module 10, the third live wire connector L3, the third switch K3, and the corresponding socket unit 20a in the third socket module 203 is disconnected, and the power supply unit 2 cannot supply power to the external device through the rack-mounted power distribution unit 1.

[0030] Specifically, the specific forms and setting methods of the first switch K1, the second switch K2, and the third switch K3 may include, but are not limited to, one or more of the following situations.

[0031] In the first situation, at least one of the first switch K1, the second switch K2, and the third switch K3 is a hydraulic switch. The hydraulic switch may be, but is not limited to, a hydraulic electromagnetic circuit breaker. Here, the specific model of the hydraulic switch is not limited, and the designer can make a reasonable selection according to actual needs. When the current in the power supply branch is within the normal operating current range, the hydraulic switch is in the conducting state. At this time, the power supply branch formed by the connection module 10, the first live wire connector L1 (or the second live wire connector L2 or the third live wire connector L3), the first switch K1 (or the second switch K2 or the third switch K3), and the corresponding socket unit 20a in the first socket module 201 (or the second socket module 202 or the third socket module 203) is conducted, and the power supply unit 2 can supply power to the external device through the rack-mounted power distribution unit 1; when the current in the power supply branch exceeds the normal operating current range, the hydraulic switch is in the cutoff state. At this time, the power supply branch formed by the connection module 10, the first live wire connector L1 (or the second live wire connector L2 or the third live wire connector L3), the first switch K1 (or the second switch K2 or the third switch K3), and the corresponding socket unit 20a in the first socket module 201 (or the second socket module 202 or the third socket module 203) is disconnected, and the power supply unit 2 cannot supply power to the external device through the rack-mounted power distribution unit 1. Of course, in other situations, the first switch K1, the second switch K2, and the third switch K3 can also be mechanical electromagnetic circuit breakers, etc.

[0032] In the second case, at least one of the first switch K1, the second switch K2, and the third switch K3 is used to turn off when it detects that the power supply branch where it is located is overloaded, so that the corresponding socket unit 20a stops supplying power to the external device. At least one of the first switch K1, the second switch K2, and the third switch K3 is used to be in the above-mentioned off state when it detects that the current in the power supply branch where it is located exceeds the normal operating current range, so that the power supply branch where it is located is disconnected, and the power supply unit 2 cannot supply power to the external device through the rack-mounted power distribution unit 1.

[0033] In the third case, at least one of the first switch K1, the second switch K2, and the third switch K3 is used to be turned on or off under the operation of the user. The user can press the first switch K1 (and / or the second switch K2 and / or the third switch K3) to make the first switch K1 (and / or the second switch K2 and / or the third switch K3) switch between the above-mentioned on state and the above-mentioned off state. When the current in the power supply branch exceeds the normal operating current range, the first switch K1 (and / or the second switch K2 and / or the third switch K3) can automatically jump from the above-mentioned on state to the above-mentioned off state to achieve overcurrent protection.

[0034] By designing the first live wire connector L1, the first switch K1, and the first socket module 201, a separate power supply branch is formed by connecting the corresponding socket unit 20a in the connection module 10, the first live wire connector L1, the first switch K1, and the first socket module 201; by designing the second live wire connector L2, the second switch K2, and the second socket module 202, a separate power supply branch is formed by connecting the corresponding socket unit 20a in the connection module 10, the second live wire connector L2, the second switch K2, and the second socket module 202; by designing the third live wire connector L3, the third switch K3, and the third socket module 203, a separate power supply branch is formed by connecting the corresponding socket unit 20a in the connection module 10, the third live wire connector L3, the third switch K3, and the third socket module 203; the three power supply branches do not interfere with each other. When the current in one of the power supply branches exceeds the normal operating current range, only this power supply branch needs to be cut off, and the remaining power supply branches can still work normally.

[0035] It should be noted that the overcurrent protection on the power supply branches where the first switch K1, the second switch K2, and the third switch K3 are located is realized by the characteristics of the switches themselves and has no connection with the intelligent monitoring side; for example, when the current in the power supply branch exceeds the normal operating current, the user can manually switch the first switch K1 / second switch K2 / third switch K3 from the on state to the off state according to actual needs, or the first switch K1 / second switch K2 / third switch K3 can also automatically switch from the on state to the off state.

[0036] As Figure 1 shown, the connection module 10 includes a connector 11, and the connector 11 is a five-wire three-phase industrial connector 11. The connection module 10 further includes a power supply board (not shown in the figure). The connector 11 is connected to the power supply board through a cable 12, and the power supply board is also connected to the connection component 30 to provide a power signal to the connection component 30.

[0037] The first live wire connector L1, the second live wire connector L2, the third live wire connector L3, the neutral wire connector N, and the ground wire connector PE are all copper bars. The first switch K1, the second switch K2, and the third switch K3 are welded between the corresponding connectors and the socket module 20; the neutral wire connector N and the ground wire connector PE are also connected to the socket module 20. Copper has good electrical conductivity. The first switch K1 is welded between the first live wire connector L1 and the first socket module 201, the second switch K2 is welded between the second live wire connector L2 and the second socket module 202, and the third switch K3 is welded between the third live wire connector L3 and the third socket module 203.

[0038] As Figure 1 and Figure 5 shown, the rack-mounted power distribution unit 1 further includes a rack housing 50. The rack housing 50 extends along a preset direction, and the power supply board is connected to one end of the rack housing 50; the first switch K1, the first socket module 201, the second switch K2, the second socket module 202, the third switch K3, and the third socket module 203 are arranged in sequence along the extending direction of the rack housing 50. In this way, the first switch K1, the first socket module 201, the second switch K2, the second socket module 202, the third switch K3, and the third socket module 203 are neatly arranged on the rack housing 50, and it is convenient for wiring.

[0039] The socket unit 20a includes a first socket 20b and a second socket 20c. A plurality of first sockets 20b and a plurality of second sockets 20c in the first socket module 201, the second socket module 202, and the third socket module 203 are arranged in at least two rows along the extending direction of the rack housing 50.

[0040] Among them, for the first socket module 201, each socket unit 20a in the first socket module 201 may include a first socket 20b and a second socket 20c. At this time, each first switch K1 is connected to the first live wire connector L1 and the one first socket 20b of the corresponding socket unit 20a, and each first switch K1 is also connected to the first live wire connector L1 and the one second socket 20c of the corresponding socket unit 20a; each socket unit 20a in the first socket module 201 may also include a plurality (more than two) of first sockets 20b and a plurality (more than two) of second sockets 20c. At this time, each first switch K1 is connected to the first live wire connector L1 and the plurality of first sockets 20b of the corresponding socket unit 20a, and each first switch K1 is also connected to the first live wire connector L1 and the plurality of second sockets 20c of the corresponding socket unit 20a.

[0041] For the second socket module 202, each socket unit 20a in the second socket module 202 may include a first socket 20b and a second socket 20c. At this time, each second switch K2 is connected to the second live wire connector L2 and the one first socket 20b of the corresponding socket unit 20a, and each second switch K2 is also connected to the second live wire connector L2 and the one second socket 20c of the corresponding socket unit 20a; each socket unit 20a in the second socket module 202 may also include a plurality (more than two) of first sockets 20b and a plurality (more than two) of second sockets 20c. At this time, each second switch K2 is connected to the second live wire connector L2 and the plurality of first sockets 20b of the corresponding socket unit 20a, and each second switch K2 is also connected to the second live wire connector L2 and the plurality of second sockets 20c of the corresponding socket unit 20a.

[0042] For the third socket module 203, each socket unit 20a in the third socket module 203 may include a first socket 20b and a second socket 20c. At this time, each third switch K3 is connected to the third live wire connector L3 and the one first socket 20b of the corresponding socket unit 20a, and each third switch K3 is also connected to the third live wire connector L3 and the one second socket 20c of the corresponding socket unit 20a; each socket unit 20a in the third socket module 203 may also include a plurality (more than two) of first sockets 20b and a plurality (more than two) of second sockets 20c.

[0044] In the first case, the first socket 20b is a C13 socket. The C13 socket is a power socket interface that complies with the IEC 60320 standard and can be used, but is not limited to, for connecting computers, servers, network devices, and some household appliances.

[0047] In the fourth case, when both the first socket 20b and the second socket 20c are connected to external devices, the maximum total current flowing through the first socket 10b and the second socket 20c is 16A.

For example, the third fixing structure 63 can be another screw fixing structure (i.e., another perforation for another screw to pass through). At this time, another screw passes through the another screw fixing structure and is threadedly connected to another threaded hole on the server cabinet. Another example is that the third fixing structure 63 can also be a pin fixing structure (i.e., a through hole for a pin to pass through). At this time, the pin passes through the pin fixing structure and is snap-fitted with a pin hole on the server cabinet. Still another example is that the third fixing structure 63 can also be a plug fixing structure (i.e., another through hole for a plug to pass through). At this time, the plug passes through the plug fixing structure and is plug-fitted with a jack on the server cabinet. By designing the third fixing structure 63, the installation between the rack-mounted power distribution unit 1 and the server cabinet can be realized. It should be noted that the first fixing structure 61, the second fixing structure 62, and the third fixing structure 63 cooperate with each other to achieve multiple installations between the rack-mounted power distribution unit 1 and the server cabinet, which can effectively improve the installation stability between the rack-mounted power distribution unit 1 and the server cabinet.

[0051] As Figure 1 and Figure 8 shown, the rack-mounted power distribution unit 1 further includes a central control module 70. The central control module 70 is installed in the rack housing 50 and connected to the connection component 30 to obtain a power signal. The central control module 70 is located between the first socket module 201 and the second switch K2, or the central control module 70 is located between the second socket module 202 and the third switch K3.

[0052] Here, the specific installation method between the central control module 70 and the rack housing 50 is not limited, and designers can make a reasonable design according to actual needs. For example, the central control module 70 can be detachably connected to the rack housing 50 by at least one of screwing, clamping, or plugging. Another example is that the central control module 70 can also be non-detachably connected to the rack housing 50 by riveting or gluing.

[0053] Specifically, the central control module 70 includes a main circuit board 71, a display screen 72, control buttons 73, and a communication port 74. The display screen, the control buttons 73, and the communication port 74 are disposed on the main circuit board 71. The detailed design of the control buttons 73, the communication port 74, and other detailed designs of the central control module 70 can include, but are not limited to, one or more of the following situations.

[0054] In the first case, the control button 73 includes a reset button 73a and a function button 73b. The reset button 73a is used for system reset; the function button 73b is used to execute predetermined control functions such as entering the system menu, scrolling the menu, and confirming functions.

[0055] In the second case, the central control module 70 further includes a communication circuit board 75 and a port circuit board 76. The communication circuit board 75 and the port circuit board 76 are mounted on the main circuit board 71, and the communication port 74 is provided on the port circuit board 76; the communication port 74 includes at least one of a sensor port 74a, a serial port 74b, a USB port 74c, a data port 74d, and a network port 74e. Both the communication circuit board 75 and the port circuit board 76 are electrically connected to the main circuit board 71, and the antenna and communication chip in the central control module 70 can be provided on the communication circuit board 75. By designing the main circuit board 71, communication circuit board 75, and port circuit board 76 to be separately arranged, the interference between the components integrated on each circuit board can be effectively reduced, and the processing difficulty and cost are also low. It should be noted that the sensor port 74a is a temperature sensor port, and the temperature sensor port is used for communication connection with a temperature sensor (not shown in the figure) installed on the server cabinet. The temperature sensor can be used to detect the actual temperature of the server cabinet where the rack-mounted power distribution unit 1 is located. When the actual temperature detected by the temperature sensor does not exceed the preset temperature threshold, the display screen 72 can be used to display the actual temperature. When the actual temperature detected by the temperature sensor exceeds the preset temperature threshold, a warning signal will be generated, and the controller of the central control module 70 can control the display screen 72 to make a text warning prompt according to the warning signal, and at the same time, the warning information can be sent out through the external communication port.
